" whom it may concern:

I ln'iown. that l, James '1. Scrotum, a

oil the United States, residing at. ilphin, in the county oflhiiadi-ilphia l. innsylvanhi, have invented inl improvements inhlicroin- L ltJi'lL'S of which the folli'iwing is ition.

niwintioo. relates to a gaging tool,, and ly to the (JlZLSL? otmicrometer piiina ,bject of the invention is n of a device ot thincharm-tor liich micrornzopic lengths and angles he accuinlely nuiasurrdtor the con l we of die makers, plane setters and "hers.

urr objectoil the invention is the non of a device of this cha11actcr inn,- blocl z thereof may be acouc i and looked; in adjusted poniivherebythe desired microscopic or angles may be obtained.

object of the invention is the a dtwice of this charanter which i I, o!coinitruction, thoroughly rcliat in operation, and inexpenlzllllllll'fi.

Fig. M is an end view thereof.

Similar reference characters indicate corrcrspong linp' parts throughoutthe several views of the drawings.

llellerringg to the drawings by 1nunorals,- the ire comprises atriangular-shaped base ii, preferably conslrluzted from metal providedwith a llat bottom edge ii, a forivardly inclined top edge 7, and a rearinwardly arched edge :3, the inclined top edge 7 bring prov idcd with achannel the same being coextensive therewith and opening throughopposite ends thereof to provide spacei'l parallel guide tracks 10, andthe base ido almtnient shoulder 13 spaced from the onatller end ot thebase, for a purpose as will be heroinattcr more fully described.

The inner lace-2e of the tracks are pro" vided with dove'lail shapedguide or run' ways 1-1, in which slidably fits a correspondingly shapedrib 15 of a movable micrometer block Ll}, the game being formed in itstop face with steps 17 and 18, respectively, the planes ol. which beingparallel to the bottom edge (S- of the base. Formed on and at a pointintermediate the ends of the rib 1.5 is a split lug 19, provided with aninternally threaded eye 20', in which is engaged an adjostling screw21.,wthe snare being disposed in the channel 9 formed in the base 5, therib if being provided with a semi-circular shaped groove 22 adapted .toreceive one-half of the diameter of the screw when engaged in the lug19, whereby the block 16 may be easily adjusted u )011 the traclm 10 atthe inclined edge 7 o the base. This split lug l!) of the movable blockit is )rovided with a binding screw E33 disposed transversely thereinand is designed to tighten the lug about the adjusting screw 21, whendesired.

The adjusting screw 21, at one end rcdnced to form a handle extension orstem 3 i, and at the inner end thereof an annular 25, the handleextension or stem atably engaged in a centering llich is rcinovablysecured in at the rear end thereof, the said collar being held in placeby means of screw members 27 passed Qttbeing rot collar 26, w

through opposite sides of the base and en-.

and extending throughthe central web l2 16 in adjusted position thereon.

the movable block 16 is positioned at the prising a triangular-shapedbase having a in the channel 9 thereof are reinforcing screws 29, thelatter being disposed transversely and extend through opposite facesAlso threaded in the base of the base. transversely thereof at a pointintermediate the reinforcing screws 29 is a binding screw 30 providedwith a winged head 31, and is adapted to inwardly displace the paralleltracks 10 for clamping the movable block smaller end of the base 5, sothat its-lug will abut against the shoulder 13 formed in the central.web 12in the base 5, so that the steps 17 and 18 on the block will be ina plane at the lowest parallel point of adjustment thereof.

Provided in one side face of the base 5, contiguous to the top edge 7thereof, is a graduated scale 32, the same being cooperative with apointer mark 33 provided in the side face of the movable block 16,whereby on adjustment of the latter, the degree of movement of the samemay be ascertained by the said scale 82 for the convenience of theoperator of the device.

In the steps 17 and 18 of the movable block 16 are formed internallythreaded sockets 3 1, each of which is adapted to-detachably receive avertical post, comprising a plurality of cylindrical shaped sections 35,the same being of uniform cross sectional diameter with respect to eachother, and the outer surface thereof are provided with knurled portionsan, whereby the said sections may be turned for connecting the same orthe detachment of one from the other. Each section of the post isprovided at one end with a reduced threaded lug 37 adapted forengagement within a socket 38 formed in the ai'ljaccnt end of thesection, contiguous thereto. Thus when the sections 35 of the post arejoined together, the said post is designed to determine the height ofthe work. It is seen that the length of the post may be increased ordecreased if desired. Also, this post is capable Normally, l

noaonre be ascertained. The turning knob 28 is provided with an outerknurled surface 42 which enables the hand of the operator to firmlygripthe same for the turning of the adjusting screw when setting the movableblock 16 on the base 5 of the device.

It is seen that the microscopic angles and lengths may be ascertained bythe device.

From the foregoing description, taken in connection with theaccompanying draw ,ings, it is thought that the construction and5operat1on of the invention will be readily understood, withoutrequiring a more eX- ,tended ezrplanatiomand therefore the same has beenomitted' l/Vhat is claimed is: 1.

,4. device of the class described comprisiflg a .tr1angular-shaped basehaving a channel in its inclined edge, a movable block slidably fittedin the channel for contacting with the inclined edge of the base, meansfor adjusting the block on the base, a sectional post having a pluralityof separable arts and engageable with the block at diferent pointsthereon, means engaging the sides of the base for the locking of theblock in adjusted position, the said base being provided with agraduated scale, and said block with a pointer formed on the block andcooperative with the scale, and a turning knob fixed to the adjustingmeans for operating the same.

5. A device of the class described comprising a base having a channel inone edge thereof, a movable block slidably fitted in the channel, anadjusting screw swiveled at one end of the channel and adjustablyengaged with the block for moving the same, a sectional post adapted fordetachable connection with the block at different points thereon andhaving separable parts, the said base being provided with a graduatedscale, and said block with a pointer cooperative with the scale, and aturning knob fixed to one end of the adjusting screw, the

said block being provided with a plurality of steps forming seats forthe said sectional 0st. p 6. A device of the class described comprisinga triangular-shaped base having a channel i;; ,its inclined edge, amovable block slid-ably fitted in the channel for contact with theinclined edge of the base, an adjusting screw swiveled at one end of thechannel and adjustably engaged with the block for moving the same, asectional post detachably engaged with the block, means engaged in thebase for locking the block in adjusted position, said base beingprovided with a graduated scale, and said block with a pointercooperative with the scale, a turning knob fixed to one end of theadjusted screw and having a graduated scale, said block being providedwith a plurality of steps forming seats for the sectional post,

and a removable collar fixed to the base and centering the adjustingscrew and having a pointer cooperative with the last named scale.

In testimony whereof I affix my signa' ture in presence of twowitnesses.
